Note: Each number is the square of a composite number except `190.`

Note: prime numbers `2, 3, 5, 7, 11, 13` have successively been subtractef. So, `100` is wrong. It must be `(108 - 11) i. e 97.`

Note: The pattern is `1 xx 3, 2 xx 5, 3 xx 7, 4 xx 9, 5 xx 11, 6 xx 13, 7 xx 15` etc.

Note: Double the number and add `1` to it, to get the next number. So, `160` is wrong.

Note: Alternately, we add `4` and double the next. So, `132` is wrong.

Note: Not available

Note: Each number is the preceding number multiplied by `- 2. So, the missing number is `- 128`

Note: Number are alternately multiplied by `2` and increased by `3` So, the missing number `61 xx 2 = 122`

Note: Numbers are `1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2` So, the next number is `8^2 = 64`

Note: Numbers are `1^3, 2^3, 3^3, 4^3, 5^3, 6^3.` So, the missing number is `7^3 = 343`.
